FILL AND VENT FITTING DEVICE.

Specification of Letters Patent. Pat nted Mar. 12, 1912.

Application filed March 14, 1910. Serial No. 549,360.

To all whom it may concern:

Be it known that I, HARRY M. BOWSER, a citizen of the United States, residing at Fort Wayne, county of Allen, and State of Indiana, have invented certain new and useful Improvements in Fill and Vent Fitting Devices, of which the following is a specification.

This invention relates to fill pipes for oil or any other combustible fluid in connection with which it is desirable to provide a closed inlet.

The primary object of the invention is to provide an improved construction, combination and arrangement of parts in a device of this nature according to which the fill pipe will be effectually closed against the admission of rain or dirt while at the same time providing a free discharge of any excess of gas as well as for the inlet of air necessary to replace the liquid extracted from the tank.

Another object is to provide an improved fill and vent fitting device having separate and distinct passages for the inlet of the fluid and the outlet of the gases.

Other and further objects will appear in the specification and be more specifically pointed out in the claims, reference being had to the accompanying drawing showing an exemplification of the invention.

In the drawing, Figure 1 is a vertical section of a tank provided with my improved device. Fig. 2 is a detail plan view of a pedestal for supporting the inner tube from the top of the outer pipe. Fig. 3 is a section on the'line III-III of Fig. 2. Fig. 4 is a section of a frusto-conical screen for screening the apertures in said pedestal.

Referring to the embodiment shown in the drawings, a tank 1 provided with a circular opening 2v has rigidly mounted thereon an annular collar 3 extending around said opening. Said collar 3 is provided with an annular flange 4. by means of which the collar is secured to the shell of the tank by means of rivets 5, the joint between the annular flange and the shell of the tank being preferabl calked. Projecting upwardly from t e tank 1 is an outer pipe 7 which is mounted in the collar 3 by a screwthreaded connection. Within the outer ipe 7 and concentrically mounted therewit is an inner tube 8 having its wall spaced from the outer tube to provide an annular passage 9 for the outlet of gas when it reaches an undesirable pressure.

In order to provide means for supporting the inner tube in proper relation to the outer pipe, a pedestal or annular supporting member 10 is mounted upon the upper end of the outer pipe 7, said pedestal being provided with an annular base flange 11 and a plurality of apertures 12, through which the annular space 9 is placed in communication with an air space to be resently referred to. The inner tube is adapted to be suspended from the pedestal 10 by an annular flange 13 which overreaches the upper end of the pedestal 10. In order to properly screen the annular passage 9, I preferably employ a frusto-conical screen 14, as shown more clearly in Fig. 4, which is adapted to fit within the annular pedestal 10 and to be held in position on the upper end of the outer pipe 7 by the annular flange 11 of said pedestal, which is seated upon and clamps the flanged portion 15 of the screen to said pipe. Threaded to the upper end of the outer pipe 7 is a sleeve coupling 16 which serves to secure a cap 17 to said pipe, said coupling being provided with a plurality of lugs 18 which are adapted to engage the annular flange 11 of the pedestal 10, thus securely fastening said pedestal on the upper end of the pipe 7. The cap 17 is preferably threaded to the coupling 16, and depending from said cap 17 preferably at the center thereof is an automatic venting device 18. By reference to Fig. 1 it will be seen that the automatic venting device 18' comprises a ball valve adapted to permit the escape of gas under pressure from within the tank, and a second ball valve communicating with the central tube of the venting device above the first valve to permit the inflow of fluid through the venting device to the tank. The cap 17 is so constructed and disposed as to provide an air space at the top of the fill pipe which is common to the annular passage 9 and the inner tube 8.

In order to provide suitable means for preventing a flare-back in the inner tube 8, said tube is provided with a screen 19 adjacent the top, said screen being preferably of a construction tapered downwardly into the inner tube 8 so as to provide a gradually enlarged passageway for the fluid passing through said screen. If desired, the

screen 19 may be soldered onto the upper end of the inner tube 8, for which purpose it is flanged outwardly to adapt it to nest within said tube.

In order to provide means for locking the vided with a depending slotted portion 23 which is adapted-to be passed over aneye;

let or staple 24 which projects'froin the outer pipe 7 and is. adapt-ed to receive a padlock or other suitable lockingdevice. The hasp 22 is furthermore constructed and arranged to provide an air passage between the vent 18 and the outer atmosphere.

What I claim is 1. In a device for the purpose described, the combination of'a'fill pipe having separate and distinct intake and outlet passages, the outer ends of said passages being screened, and a, cap for said fill pipe provided with an automatic vent communlcat- 'ing with both of said passages.

2. Ina device for the purpose described, the combination of a fill pipe provided with separate and distinct tubular passages for the intake of the hydro-carbon and the outlet for gas, a'screen for each of said passages,

, and a cap for said pipe provided with a vent, said cap being constructed to provide a common a1r space above said passages 1n communication with said vent.

3. In a device for the purpose described, the combination of a fill pipe provided with separate and distinct tubular passages for the intake of the hydro-carbon and the outlet of gas, a screen for each of said passages, a cap for said pipe provided with a vent and providing a common air space above said passages in communication with said vent, and means for locking said cap on the fill pipe, said locking means being constructed and adapted to cover said vent and to provide an air passage from said vent to the atmosphere.

4. In a device of the character described, the combination of an outer pipe and an inner tube concentrically disposed with spaced walls, a cap for the outer pipe arranged to provide an air space above the 'upper ends of said pipe and tube, means for screening the upper ends of said pipe and tube, and a venting device mounted in the cap for placing said air space into communication with the atmosphere.

5. In a device for the purpose described, the combination of a fill pipe, an inner tube spaced therefrom to provide an annular passage, a screen for said tube, a screen for said annular passage, and a removable cap for 1 said pipe, said cap being provided with an automatic vent in communication with the space above each of said screens.
